This firefly occurs in Delaware.
This rare firefly is found in open habitats including moist meadows, hayfields, and fields with dense scrub-shrub vegetation, such as those that have been left to fallow.
Habitat loss and light pollution are the greatest threats to this species.
- We need to know more about the distribution of this species. Report your Delaware firefly sightings to iNaturalist, or consider participating in Firefly Watch!
- Turn off your outdoor lights at night so the lights of this firefly aren’t diminished by light pollution. You can read more about firefly-friendly lighting in our fact sheet.
- Avoid pesticide use, which could harm this firefly, its habitat, or its prey.
- Habitat loss is a major threat to this species. If you own land with old field habitat within the range of this firefly, consider protecting and maintaining it by mowing once every one to two years.
- More research on population size and trend, habitats and ecology, and threats is needed for this species.
